Parents have always relied on reasonable societal guardrails to protect their children when the parent cannot be around. There's nothing wrong with that expectation. Otherwise we might was well become "helicopter" parents to the extreme.
Nope-—still wrong and how we got in this problem in the first place because “parents are obeying their children” and not the other way around. No matter how hard you try, you CAN NOT legislate morality!
The FCC has standards when it comes to broadcasting over the air (even though those have eroded enormously), but over the internet it has no power.
WIFI and BlueTooth are too small of a signal for them to regulate.
